The Club for Growth's political action arm released a TV ad Monday against Idaho Rep. Mike Simpson, hitting the eight-term Republican on his vote for the Wall Street bailout in 2008 — a key point of contention for the conservative outside group.

The 30-second spot is a fact-check on Simpson's claim in a recent ad that he voted to repeal the Troubled Assets Relief Program, better known as TARP. The ad utilizes video footage of Simpson speaking at an event in 2010, telling an audience that he voted for TARP.

"I voted for the $700 billion bailout," Simpson says in the ad. "Everybody got that? My name is Mike Simpson, I voted for the $700 billion bailout."

The ad is backed by a six-figure buy on broadcast and cable, according to a release from the club.

Idaho's 2nd District is rated Safe Republican by Rothenberg Political Report/Roll Call.
